As we all know, for burnishing large diameter and deep hole, there are some difficulties in following:
- If the cutter body is long, also there is high requirement for radial runout of clamping tool.
- For cooling system, there is an inner-cooling device in the tool, so there are high requirements for equipment.
- Chip removal difficult
- High requirement for equipment rigidity
At present, RBT blind hole burnishing tool can be solved the difficult point (workpiece with large diameter and deep hole). Today, we will introduce how to roller burnish blind hole with φ50mm, and length 110mm.
Workpiece profile:
1) Material: Stainless Steel

Processing Requirements:
1) Processing dia.: 50mm
2) Processing length: 110mm
3) Variance in dimensions (mm): 0.07
4) Shank Model: Morse Taper shank L2 3#*98
5) The ovality of metal hole after bored is within 0.01 on the diameter of 50mm
Above all, RBT recommend φ50 blind hole roller burnishing tool, which the picture of real product in following:
